acpi: Correct reset handling in acpi_device_add_power_res()

2020-11-06T01:51:30+00:00

If there is no reset line, this still emits ACPI code for the reset GPIO.
Fix it by updating the check.

x86: Allow putting some tables in the bloblist

2020-11-06T01:51:28+00:00

At present all tables are placed starting at address f0000 in memory, and
can be up to 64KB in size. If the tables are very large, this may not
provide enough space.

Also if the tables point to other tables (such as console log or a ramoops
area) then we must allocate other memory anyway.

The bloblist is a nice place to put these tables since it is contiguous,
which makes it easy to reserve this memory for linux using the 820 tables.

Add an option to put some of the tables in the bloblist. For SMBIOS and
ACPI, create suitable pointers from the f0000 region to the new location
of the tables.

x86: acpi: Support generation of the DBG2 table

2020-09-25T03:27:17+00:00

Add an implementation of the DBG2 (Debug Port Table 2) ACPI table.
Adjust one of the header includes to be in the correct order, before
adding more.

Note that the DBG2 table is generic but the PCI UART is x86-specific at
present since it assumes an ns16550 UART. It can be generalised later
if necessary.

dm: acpi: Use correct GPIO polarity type in acpi_dp_add_gpio()

2020-09-25T03:27:14+00:00

This function currently accepts the IRQ-polarity type. Fix it to use the
GPIO type instead.
